Description
Technical field
The present invention relates to Hall current sensor fitting structural assembly fields, more particularly to full PCB installing types closed-loop type is suddenly
That current sensor mounting structure.
Background technology
Current sensor is a kind of using very extensive electronic building brick, it is widely used in various Semiconductor Converting Technologies, friendship
It flows in the automatic control field using electric current as control object such as numerical control device.
Many to the non-cpntact measurement and monitoring method of electric current, Hall current sensor is extensive because of its excellent cost performance
Using and form industrialization；And full PCB installing type closed-loop type Hall current sensors are generally used for the measurement of 100A or less electric currents
And monitoring.Hall current sensor usually has two kinds of open loop, closed loop operating modes, the full PCB installing types Hall electricity of both of which
Flow sensor is generally used single air gap, single multilayer punching toroid structure, the current sensor of this magnetic structure
It has the following problems：
One, full PCB installing types open ring type Hall current sensor because electric current number of ampere turns it is small, for increase electric current number of ampere turns, just
Grade must be around multiturn, i.e., the coiling multiturn coil on single air gap, single multilayer punching toroidal core, since magnetic core size is smaller,
High-volume coiling processing is relatively time consuming, bothersome；And to ensure sensor output amplitude, then circuit amplification factor is big, the zero of sensor
Point, amplitude are debugged repeatedly so that open ring type Hall current sensor production efficiency is too low, cannot achieve efficient mass production.
And the magnetic structure of this current sensor determines that its magnetic core remanent magnetism is too big, seriously affects small current measurement precision, in its survey
Ranging from 3 times of rated current are measured, precision is preferably 1.5%FS, and small signal bandwidth can only also accomplish 0-50KHZ.
Although two, full PCB installing types closed-loop type Hall current sensor with multilayer punching to insert ring core structure and just,
Secondary coil distinguishes coiling and realizes batch production, but the exit of its primary thick line circle is not easy accurately to install and fix, and influences batch
Production efficiency；And multilayer punching is rectangular to the section for plugging in toroidal core, adds skeleton, coil tracks are long, and internal resistance is big, sensing
The linear measurement range of device is small, anti-saturation energy force difference；For reduce Coil resistance, overstriking line footpath, both increased sensor volume and
Weight is unfavorable for sensor miniaturization, and consumes more copper materials, and sensor cost is made to increase, and this structure is without fundamentally
Solve the problems, such as the remanent magnetism of magnetic core, Hall current sensor power supply is lagged behind and supervised especially many control systems in time
Electric current is controlled, i.e., first has monitor current then to add sensor power supply.The remanent magnetism problem of magnetic core is more prominent in this case,
And the remanent magnetism of magnetic core increases in accumulation as time goes by, is 2 times of rated current in its measurement range, precision is preferably 1.0%
FS, -3db bandwidth are 0-100KHZ.
Three, since the primary and secondary coil of full PCB installing types closed-loop type Hall current sensor is located at magnetic core both sides, add
It is fixed on pcb board after the completion of work, then is installed in shell with the pin on skeleton, with casting glue overall perfusion, at the beginning of
Secondary coil all seals, and in larger current or when working long hours, the heat that coil generates can not emit, and Hall current passes
The temperature of sensor shell significantly increases, and zero, the amplitude drift of Hall current sensor are bigger, seriously affect Hall current
The measurement accuracy of sensor and resistance to environment capacity！Also the application field and versatility of Hall current sensor are limited！
